Notes:

• Design this circuit diagram on veroboard or pcb using 18 pin IC base.
• Program your PIC (pic16f84 or pic16f84a) using PIC Programmer with ic-prog programmer software and this .HEX file. You can follow these instructions.
• Install PIC on IC base.
• Supply power to your circuit and set time using PB1 and PB2.

Thats all.
